ABSTRACT

An air conditioning system for an enclosure in which a heat exchange medium flows in a looped pipe along a wall of the enclosure to and from a temperature regulating unit for heating or cooling the heat exchange medium, the return loop of the pipe being enclosed within an air ventilating shaft spaced from said wall and being provided with fins for directing the air downwardly while the other pipe loop is provided with fins for directing the conditioned air upwardly through an operture in the wall.

3 Claims, 4 Drawing Figures CONVECTORS AND TO SYSTEM EMPLOYING SAMEBACKGROUND OF THE INVENTION This invention comprises improvementsrelating to air conditioning systems for an enclosure such as adwelling.

It is known to arrange elongated horizontally extending convectors inthe horizontal parts of a piping system carrying a liquid heating orcooling medium, said convectors comprising in combination a number ofparallel and vertically extending sheet metal fins fixed to one or anumber of pipes forming a part of said piping system.

When using such convectors for heating air in dwellings, the air closeto the floor is caused to flow upwardly between the fins and receiveheat from them. The convection currents thus created promotes the mixingand circulation of the heated air thereby to heat all the air within thepremises.

The piping system usually includes vertically directed pipes inaddition, but such pipes have not previously had convectors connected inthem since the fins would then be disposed horizontally and be unable toguide the heated air in a flow directed upwards and thereby createself-circulation of the air in the premises.

The present invention provides, from one aspect, an assemblage of finsand opposite, parallel, elongated, sheet-form side parts for aconvector, the fins extending transversely of and between the side partsperpendicular thereto, the fins being all similarly inclined at an acuteangle with respect to the lengthwise direction of the side parts.

The present invention also provides a convector comprising a finned pipewherein the fins extend transversely of and between opposite, parallel,elongated sheet-form side parts perpendicular thereto, the fins beingall similarly inclined at an acute angle with respect to the lengthwisedirection of the pipe.

The present invention still further provides a convector systemcomprising a piping system having vertically extending pipe runsincluding convectors as defined in the immediately preceding paragraph.

FIG. 2 is a diagrammatic view showing a further convector systemaccording to the present invention;

FIG. 3 is a diagrammatic view showing a still further convector systemaccording, to the present invention;

FIG. 4 is a partial perspective view to a larger size and partly brokenaway showing a convector according to the present invention.

DESCRIPTION OF A SPECIFIC EMBODIMENT Referring to the accompanyingdrawings, a closed loop piping system is shown which is assumed toinclude a boiler or refrigerating unit, and for the purposes of thefollowing description hot water circulates through the pipes.

The piping system consists of vertically extending pipe lines 10,10 andhorizontally extending pipe lines In the horizontally extending pipes10", convectors 11, having vertically extending fins 12 are arranged.

Vertically extending convectors 11' are connected in the verticallyextending pipe runs 10,10. The convec- LII parts may be in two parts asdescribed in my copending patent application Ser. No. 209,188, filedDec. 17, 1971, now abandoned whereby the fins and side parts may beassembled about the pipes 10,10 with the pipes already in position.However, the convectors 11' may be assembled separately and installed inthe pipes 10,10 in the usual fashion. The assemblage of fins and sideparts would be as described in the above identified patent applicationexcept only that the fins would be inclined at an acute angle to thelengthwise direction of the elongated side parts.

As shown in FIG. 1, the two vertically extending pipe lines 10,10, arearranged one on each side of windows 14, and convectors 11 havinginclined sheet metal fins are arranged one alongside each window. Thefins 12' of the convectors 11' on opposite sides of each window areinclined relatively to one another and to direct air upwardly and acrossthe window, as shown by the arrows in the figure. A curtain of heatedair thus covers each window, the air moving upwardly and mixing withcolder air to be recirculated by the natural convection currentsgenerated in the room.

As shown in FIG. 2, if the two vertically directed pipe lines 10,10 arearranged on the same side of the windows 14, the fins 12' of theconvectors 11 are similarly inclined to direct air upwardly across thewindow.

As shown in FIG. 3, the piping system with the convectors 11 may bearranged in a vertically extending conduit 15 within a wall of amultistorey building to heat rooms 16 bounded on one side by the wall. Avertically extending air ventilation shaft 17 is provided having itsupper end connected to an air intake blower 18 and its lower end openingto a boiler room 19, in which a boiler 20 is placed. The pipes 10,10 areconnected in a closed loop with the boiler and the return pipe 10 ispositioned in the ventilation shaft 17. The wall has apertures 21opening one into the lower part of each room 16 for the admission ofheated air from the conduit 15 and the pipe 10 is disposed adjacent theapertures 21 and has fins 12 directed upwardly towards the walls 16 andthe apertures 21. This arrangement of the fins causes the heated air torise upwardly through the conduit 15 and through the apertures 21 towarm the rooms. The convector fins within the ventilation shaft directthe fresh air downwardly, the air at the same time being heated as itpasses over the fins. The convector systems described may be used forcooling the rooms. The air flow will then occur in the oppositedirection a liquid cooling medium flowing in the piping system.
